Great for professional fine art, brush lettering, illustrations, journaling & more, the Intensity Dual Tip Marker gives artists exceptional versatility with each two-sided, fineliner pen. One end of the fineliner features a durable brush tip that can create fine, medium & broad strokes. The other end of the fineliner has a fine tip, delivering consistent precision for delicate linework & hand lettering. Each colored pen features bold, water-based ink that won't bleed through paper. Results could vary based on paper characteristics.
